标准范围

IEC 60255-27:2023规定了额定交流电压高达1000 V或额定直流电压高达1500 V的测量继电器和保护设备的产品安全要求。本文件规定了必要的安全要求，以最大限度地减少因电击或对用户和财产造成的火灾和危险。本文件仅规定了产品安全要求；不包括设备的功能性能。本文件涵盖了机柜、机架和面板中安装和使用设备的所有方式。本文件还适用于辅助设备，如分流器、串联电阻器、变压器、辅助控制面板、显示设备等。，与测量继电器和保护设备一起使用，并一起进行测试。

IEC 60255-27:2023 specifies the product safety requirements for measuring relays and protection equipment having a rated AC voltage up to 1 000 V, or a rated DC voltage up to 1 500 V. This document specifies essential safety requirements to minimize the risk of fire and hazards caused by electric shock or injury to the user and property. This document specifies only product safety requirements; functional performance of the equipment is not covered. This document covers all the ways in which the equipment can be mounted and used in cabinets, racks and panels. This document also applies to auxiliary devices such as shunts, series resistors, transformers, auxiliary control panels, display devices, etc., that are used in conjunction with measuring relays and protection equipment and are tested together.
